A vascular surgeon or phlebologist (a doctor who specializes specifically in vein conditions) is the most common type of specialist who treats varicose veins. Depending on your situation, an interventional radiologist or dermatologist may also provide treatment. Your primary care doctor can evaluate your veins initially, but they’ll typically refer you to one of these specialists if treatment is needed.
Vascular Surgeons and Phlebologists
Vascular surgeons are the broadest specialists for varicose veins. They handle everything from mild cases to severe venous disease, and they’re trained in both traditional surgery and newer minimally invasive techniques like laser therapy and radiofrequency ablation. A phlebologist is a doctor whose practice focuses exclusively on vein disorders. Some phlebologists come from a vascular surgery background, while others trained in other fields and then specialized in veins through additional certification.
If your varicose veins are causing pain, swelling, skin changes, or other complications beyond cosmetics, a vascular surgeon or phlebologist is generally the right starting point. They can diagnose the underlying cause, which is often a problem with the valves inside your veins allowing blood to flow backward, and recommend a full treatment plan. The 2023 clinical practice guidelines from the Society for Vascular Surgery, American Venous Forum, and American Vein and Lymphatic Society outline evidence-based recommendations for managing varicose veins, and vascular specialists are the ones most familiar with applying those guidelines.
Interventional Radiologists
Interventional radiologists treat varicose veins using image-guided, minimally invasive procedures. Their specific advantage is expertise in ultrasound and other imaging technology, which lets them visualize veins in real time during treatment. This precision matters for procedures like endovenous laser treatment, radiofrequency ablation, medical adhesive closure (VenaSeal), ultrasound-guided sclerotherapy, and microphlebectomy, all of which interventional radiologists perform as outpatient procedures.
If your primary care doctor or another specialist has already confirmed you need a procedure, an interventional radiologist is a strong option, particularly for cases involving veins that are harder to access or that require careful imaging guidance.
Dermatologists
Dermatologists primarily treat spider veins and smaller varicose veins, often using sclerotherapy (injecting a solution that closes the vein). If your main concern is the appearance of visible veins on your legs rather than pain or swelling, a dermatologist may be the right fit. The American Academy of Dermatology notes that treatment performed solely to improve appearance is generally considered cosmetic, meaning you’ll likely pay out of pocket.
That said, dermatologists also recognize that varicose veins can cause pain, fatigue, and serious complications like blood clots or open sores. When symptoms go beyond cosmetics, they may treat the condition or refer you to a vascular specialist.
What Happens at Your First Visit
Regardless of which specialist you see, the diagnostic process is similar. The doctor will examine your legs while you’re standing, looking for visible veins and swelling. The key diagnostic tool is a duplex ultrasound, a painless imaging scan that shows how blood flows through your veins. The ultrasound measures whether blood is flowing backward through faulty valves. Backward flow lasting longer than half a second in most veins is considered abnormal, confirming a condition called venous insufficiency.
This ultrasound is important not just for diagnosis but also for insurance purposes. Most insurance companies require imaging results that document backward blood flow before they’ll approve treatment.
How Treatment Options Compare
The treatment your specialist recommends depends on the size and location of your varicose veins, along with the severity of your symptoms. The main options break down into three categories:
- Endovenous laser ablation or radiofrequency ablation: A thin catheter is inserted into the vein and uses heat to seal it shut. At one year, 97% of treated veins remained closed after laser ablation, matching the success rate of traditional surgery. Only 1% of laser patients needed additional treatment within that year.
- Foam sclerotherapy: A foam solution is injected into the vein to close it. This works best on smaller veins. For larger veins (9 mm or wider), the closure rate drops below 40% at one year, and 15% of patients in one clinical trial needed retreatment. For veins under 6 mm, though, closure rates reached about 75%.
- Surgery (vein stripping or removal): The problem vein is physically removed. This has a 97% success rate at one year but is more invasive and involves longer recovery. It’s less commonly used now that laser and radiofrequency options are available.
Vascular surgeons can perform all three. Interventional radiologists typically focus on the catheter-based and injection-based options. Dermatologists most often use sclerotherapy.
What Insurance Typically Requires
If your varicose veins cause medical symptoms, treatment is often covered by insurance, but there are hoops to jump through. Most insurers require documentation that your veins are causing health problems: pain or heaviness in the legs, swelling that doesn’t respond to conservative treatment, skin changes or ulcers from poor circulation, bleeding, inflammation, or confirmed backward blood flow on ultrasound.
Before approving procedures like laser therapy or radiofrequency ablation, many insurance companies also require proof that you’ve tried and failed conservative treatments first. This usually means wearing compression stockings for a set period (often three to six months), elevating your legs regularly, and increasing physical activity. Your specialist will need to document these attempts and their results in your medical records. If conservative measures don’t resolve your symptoms, the insurer is more likely to approve a procedure.
Purely cosmetic treatment for veins that aren’t causing symptoms is almost never covered. If you’re unsure whether your case qualifies, your specialist’s office can usually check with your insurer before scheduling a procedure.
Choosing the Right Specialist
For most people with symptomatic varicose veins, a vascular surgeon or phlebologist is the most straightforward choice. They can manage the full spectrum from diagnosis through treatment and follow-up. If you already know you want a minimally invasive, image-guided procedure, an interventional radiologist is equally capable. For smaller spider veins or cosmetic concerns, start with a dermatologist.
Your primary care doctor can help you decide which referral makes the most sense based on your symptoms, the size of your veins, and what’s available in your area. Many vein clinics now house multiple specialties under one roof, so you may not need to choose between them at all.
